Stegosaurus armatus (Owen). 

 Syn. Omosaurus armatus, Owen (supra, i. p. 177). 



Stegosaurus hastiger (Owen). 

 Syn. Omosaurus hastiger, Owen {supra, i. p. 179). 



Genus EUSCELESAURUS, Huxley 1 . 



Imperfectly known and provisionally referred to the Stegosauridce. 

 Limb-bones solid 2 ; femur with a large inner trochanter ; tibia 

 with small proximal expansion, and apparently suturally connected 

 at its extremities with the fibula ; astragalus and calcaneum respec- 

 tively united closely with the tibia and fibula. 



The caudal vertebrae, phalangeals, and a pelvic bone which appears 

 to be the preacetabular portion of a pubis, figured by Pischer in the 

 ' Arch, du Museum,' ser. 1, vol. vi. pi. xi. (1870), were obtained with 

 the undermentioned specimens, and doubtless belong either to the 

 present or the next genus. The vertebrae appear to be of an 

 Iguanodont type. 



Euscelesaurus browni, Huxley 3 . 



The type species. Approximating in size to Iguanodon mantelli, 

 the femur measuring about one yard in length. 

 Bab. South Africa. 



The following specimens include the types, and were obtained at 

 Aliwal North 4 , in the Stormberg range, from the Stormberg beds 

 of the Karoo system. They were presented to the Museum in 

 1888 by Professor T. E. Huxley. 



R. 1625. The imperfect right femur. The type specimen ; described 

 by Huxley in the ' Quart. Journ. Geol. Soc' vol. xxiii. 

 pp. 1-4. Both articular extremities are wanting, and the 

 greater portion of the inner trochanter is broken away. 

 In some respects the contour of this bone is nearer to the 

 femur of Iguanodon than to that of Stegosaurus. 



R. 1625 a. The proximal extremity of the left tibia and fibula. 

 Noticed by Huxley, op. cit. p. 4. The part regarded in 

 that notice as the cnemial crest appears to be the head of
